What is Commercial Advisors

[Xiuyuan W.]

I am sorry to ask a very amateur question, what is commercial advisor? I am considering to buy net leased properties, but instead of working with traditional real estate agent, there are advisors who would act as my agent? I am confused, is this the same thing? what is the difference between advisor and say KW commercial agent?

By the way, what is the exact difference between brokers/realtor/agent/advisor in US?

Please notice me if there would be any difference regarding legal side as well.

Thanks for input.
